Out of body experiences and seeing the light at the end of the tunnel (Heaven)??
“The “light at the end of a tunnel” can be duplicated by putting pilots in an ultracentrifuge. As blood drains from their head, the outer rim of their retina loses blood, so you only see the center of the retina, so you see a light at the end of the tunnel. The “light at the end of the tunnel,” caused by a drop in blood pressure, can also happen in an accident, so therefore people think they have died and seen heaven.
“Out of body experiences” can also be duplicated by electrically stimulating certain regions of the brain. By stimulating the boundary between two areas of the brain, it gets confused. To make sense of these contradictory signals, the brain interprets this as being outside the body. This effect can simply be created by an electrical probe to the brain.”
